stock tank moves upwardly to immerse thedies; to allow the water or pulpsolvent in the die box to run out by gravity as well as by suction; tohave means of agitating the pulp solution in the stock tank; toconstruct a machine wherein the dies are rotated in one direction only;and generally, to improve on the machines now in use, and to supply amachine very economical of operation and of construction.

This machine is one wherein a female and a male die are used, the diesbeing designed to hold a plurality of 'laminations formed to correspondto the shape of the finished article. The laminations may be arranged ormounted in any suitable manner, so as to cause the female die to becomecovered or coated with the pulp substance when the die box enclosing thelaminations is submerged into a pulp mixture and vacuum applied to causethe solvent or water to run through or between the laminations. Thefemale die must be first coated with the pulp substance, after whichthemale die is operated to engage the female die and give the article itsfinished form; and as Will be explained later, the male die alsooperates' to remove or pick the finished pulp article from the femaledie.

Referring to the drawings, 10 is the base of the machine mounting theframe 11. 12

is the stock tank havinglaterally-extending brackets 13 formed to slidein the tracks 14 provided in two of the inner faces of the frame 11.pivots 17 projecting out from two sides thereof, by means of which it issupported by the eccentric rods 18. I The tank is fed by the pipe 23,and a suitable overflow (not shown) is provided in order to keep thelevel of the pulp solution at any predetermined level according to thesize of the dies used.

15 is a horizontally-arranged shaft rotat- The tank is provided with theably mounted in the frame 11 under the tracks 14 and underthe tank 12;the shaft rigidly mounts, adjacent to two sides of said tank, theeccentrics 16. 18 are eccentric rods pivotally mounted between thepivots 17 and the eccentrics 16. As the shaft rotates, the tank 12 m0vesup and down in the tracks 1 1.

-19 is the drive shaft, suitably journalled in. the frame 11 and havingthe drive pulley 20 rigidly secured thereupon; 21 are two gears rigidlycarried by the shaft 19 adjacent two of the outside faces of the frame,and 22 are two gears rigidly carried by the shaft 15 and meshing withthe gears 21. The tank is therefore actuated vertically by the rot-ationof the drive shaft 19.

'Each of the gears. 22 is slotted to receive a stud or crank pin 25adapted to be adjustably secured in the slot; 28A are levers, one oneach of two sides of the frame, pivoting on the studs 28; 27 are twocrank rods each pivotally mounted between the crank pin 25 and the lowerend of the lever 28A. The crank rods 27 are preferably slotted at oneend, as shown. The gears 22 are slotted in order to regulate the'strokeof the crank pins 25, this being necessary'when the number of moldingdies used in the machine is to be varied. f The drawings show theapplication offour dies, uniformly spaced at 90, each die being rotatedthrough 90 for each revolution of the shaft 15; if eight dies are to beused, it follows that the studs 25 must be so adjusted in the gears 22as to cause the dies to rotate through an angle of 45 for everyrevolution-of the shaft 15.

2 9are two levers, one on each of two sides of the machine, pivoting at30; and 31 are two levers rigid or movable with the levers 29,the-levers 31being slotted at 32 to slidwith, the reduced ends rotatingin the bearings 37 and extending therethrough. Rotatabl-y mounted on andadjacent each end of the reduced shafts 36 is a disc or ratchet plate37A pivotally carrying the pawl '38 coactin 'with a ratchet 39 which isrigidly carried y the reduced end adjacently of said disc 37A. 106 areconnecting links each piva otally connected-between the disc 37A and theupper end ofthe lever 29. As the links 106 travel towards the shaft .35,the disw 37A rotate in an anti-clockwise direction, causing the pawls 38to slide over or upon the ratchets 39; and as the links travel away fromsaid shaft, the discs rotate in a clock wise direction,- causing theratchets and the shaft 35 to rotate with said discs owing to theengagement of the pawls with said ratchets. In other words, the shaft 35and the die brackets'mounted thereon are rotated only in a clockwisedirection and at regular intervals, the die brackets rotating through anangle of 90 for every revolution of the shaft 60 are a pair ofparallel-spaced horizontal rods rigidly secured to the bosses 63 and 64of the extension brackets 56, and each slidably mounting the slidingsplit bearing 61; 62 is a helical spring encircling each ofthe rods 60,bearing at one end upon the boss 63 and fitting at the other end in arecess formed in the split bearing 61; the springs are tensioned tonormally hold said split bearings against the outer bosses 64.

105 is a hollow shaft of similar construction to shaft 35, having thereduced plug like end shafts 36 rigid therewith and rotating in thesplit bearings 61 through which they extend. As the shaft 105 dependsupon the split bearings 61 which slide on the horizontally-arranged bars60, it follows that the shaft is movable in a horizontal plane. Theshaft 105 detachably mounts the four evenly-s aced die brackets 108,108A, 10813, and 108 lying in a same vertical plane with the diebrackets 40, 40A, 40B, and 40C and at right angles to the axis of theshaft 35.

50 are two gears of equal pitch diameter to that of the gears 22, eachrotatably mounted on a spindle orstud 51 which pr0- jectsout from theframe, and being verti- 1e5- cally above and meshing with said gears 22;52 is a cam rigid androtating with each of the gears 50. I v

53 are substantially L-formed cam levers each pivotally mounted adjacenteach of two 1 7 sides of the frame by means of a stud 54, and eachhaving the roller 55 adapted to operatively engage and ride upon the cam52. The cam' 52 is made to a contour substantially as shown, the camcrank 53 remaining stationary for one half of a revolution of the cam,then uniformly rotating in an anticlockwise direction for a timeequivalent to ths of a revolution of said cam, and then uniformlyrotating in a clockwise direction for a time equivalent to th of arevolution of said cam.

. '55 is a pair of arms each pivotally mounted on a stud 57 carried onone side of g the extension brackets 56; 59 is a link of adjustablelength pivotally carried by each of the levers 55 and the crank levers53, whereby an rotation of the levers 53 is transmitte' to the levers55. The upper ends of, the. levers 55 are slotted to slidably andretatably engage the reduced ends 36 of the shaft-105. It will be seenthat the split bearings 61, and therefore the shaft 105 and the diebrackets mounted thereon, are moved horizontally against the action ofthe springs 62 bythe oscillation of the levers 55.

1 slot-115 with the pinor stud 112 which is rigidly carried by'each ofthe discs 108. As the die brackets on both the shafts 35 and 105 must besimultaneously rotated in a same direction and by equal increments of90?, itfollows that the connecting links 106 and 111 must be on oppositesides of a plane passing through the centres of said shafts.

As the shaft 105 shifts towards the shaft 35 fora time equivalent to thsof a revo lution of the cam 52 while during that time the links 111 moveaway from said shaft 35, the slots 115 are therefore provided to allowthe pins 112 to move unimpeded relatively to said links. Each of thediscs 108 is recessed in to receive the lead weight 108A by means ofwhich the disc is rotated in an anti-clockwise direction preparatory tobeing rotated in a clockwise direction by the action of the links 111. 1

. 115 are two circular discs, hereafter named indexing plates havingfour -equally spaced notches 116A in the periphery thereof, each of saiddiscs being ri idly secured on the reduced end of the sha t 35 betweenthe bearing 37 and the ratchet 39.

116 are two circular discs termed indexing plates, similar to the discs115 in shape and size, having four equally-spaced notches in theperiphery thereof, each of said discs being rigidly secured onthereduced end of the shaft 105 between the split bearing 61 and theratchet 110.-

118 are indexing fingers or plungers, each slidable in a fixed bracket119 and having the collar 120 and the roller -121. 122 are indexingfingers similar to the indexing fingers 118 inshape and size, and havingthe collar 123 and the roller 124, each of said fingers sliding in thebearing 125A formed in the split bearing 61. 125 are twocam bars,slidingly supported on two sides of the frame by thehorizontally-arranged brackets 126 and 127; the lower edge of each cambar is notched at 128 and 129 riding on or engaging the rollers 121 and124 respectively. A spring 130 encircles each of the fingers 118 and issupported-at the bottom in thebracket 119 and bears at the top upon thecollar 120, the spring being tensioned to' collar 123, the spring beingtensioned to normally urge the finger 122 upwardly. 132

are two levers, each'pivotally carried by the frame at 94; the lever isslotted at 132A to pivotally and slidably engage the pin 133 carried byeach of the cam bars 125- and having the lug133A sized and situated tobe slidably engaged by the catch or dog 134 carried by each of the gears50. The movement of each of the cam bars in one direction is determinedby the engagement'of the pin 105A with the bracket 127, and. a spring130 mounted as shown, is tensioned to normally hold the pin 105A inengagement with said bracket. The notches in the cam bars are sosituated that the rollers normally ride in said notches, so that thefingers normally en gage the periphery'of the indexing plates or thenotches 116A therein. x

The catches 134 must be so sized and located that the fingers 118 and122 will clear the notches in the indexing plates 1'15 and 116,respectively, just long enough to enable these plates to be rotatedthrough a very small angle.-

In order to absorber destroy the momentum of the die brackets on both ofthe shafts 35 and 105 before their rotation is checked after eachquarter revolution, I pro: .vide at both ends of the shafts a leatherpad 17 0 held in a metal shoe 171 which fits into a recess vin the endof the bearingcaps 172A, the brake or pad being adjusted by means of vthe cap screw 172 threadedin the cap 172A,

The die brackets for each of the shafts 35 and 105 are made as shown inFigures 19 to 21, having the flat base 42, the curved flange 41 formedto fit upon the shaft to which it is suddenly ice detachably secured,andthe four ribs 43 radiating from the central columnar shaped portion140, the portion 140 and the ribs extending between, said base andflange. The base 42' of each bracketis made flat to receive a die box 44within which are secured the laminations.

The portion 140 in each die bracket is cored to provide a passagethrough which is passed a pipe 71, the pipe being threaded at one end toreceive the el ow 75 and threaded at the other end to receive the nut 45which is countersunk or recessed in the base; By screwing the nut 45upon the pipe, the elbow may be made to bear tightly upon the inside ofthe shaft upon which the bracket is mounted. A second nut 46 is screwedupon the pipe 71'over the nut 45, the bottom of.

. the box being recessed to enclose said second nut. A second pipe 141is screwed into. the

elbow 75 and run through one of the reduced.

ends of each shaft, the outer end of said pipe being threaded to receivethe nut 142which fits in a recess made in the end face 152 of thereduced shaft. The pipes 71 and 141. and the elbow 7 5' form a linerofpiping or a continuous passage between the die box and the end face ofthe reduced shaft; four such lines or passages are provided in each ofthe shafts 35 and 105, these lines being referred .to, in the statementof operation, as the retained on the end of its respective shaftthefunction and action of which will be explained in the statement of theoperation of the machineforms a chamber, to'be termed hereinafter avacuum chamber. The contactingsurfaces between each casting and itsrigidly carriedby the disc 153 by means 0 corresponding. shaft aremachined to give a sliding fit. V

In each chamber is a wax washer or ring 150 fitting on a shoulder formedin the periphery of the hollow shaft, and also a second wax washer ordisc- 151 bea'ri'n upon the end-face 152 of the reduced sha t; 161,161A, 161B and-161C are ports or passages through the Wax washer 151 andspaced to be in alignment with the pipes 141 when the shafts 35 and 105are temporarily locked against rotation. 153 is a metal disc held in 7contact or engagement with the wax washer 151 by means of the tensionedsprings 154,

four equally-spaced recesses 155 being provided in the inner face ofsaid disc 153'to receive the nuts 156. The disc isprovided with a numberof pins 161 engaging co-acting recesses in the waxwasher 151 so as toretain or lock same with its ports in alignmer. with the pipes 157,157A, 15713 and 157 157, 157A, .157B and 157C are four pipes the nuts156, and extending out through the chamber wall 146 andloosely mountingsaid springs 154.

In the wax washer enclosed in the vacuum chamber associated withthe-shaft 35, are

'recesses or passages 162and 163 formed as shown inFlgure 4; therecesses 162 operatively connecting the ports 161A and 16115;:

in the wax washer enclosed the vacu chamber associated with the shaft105, are

The pipe 157C of castings" 143 and 144, and thepipe 157 of casting 144,are open- .to the atmosphere; the pipes 157A and 157B.

of'casting-143 are connected to a pipe 166 having the suction pump 167intermediate of its length; the pipe 157 of casting 143 is connected tothe pipe 169 having the vacuum tank 170 and suction pump 171intermediate of its length, the pipe 169 opening to the atmosphere ;.thepipe 157B of casting 144 is connected to a pipe 171 having the suctionpump 172 intermediate of its length; I V

the pipe 157A of casting 144 is connected to a pipe 173 having thesuction pump 174 intermediate of its length. The pipes 166, 171 and 173all lead to a suitable tra wherein the liquid and air are separated, thewater passing out through the pipe 164 and into a tank (not'shown), andthe air being forced into the pipe 175 and into the perforated pipe 165carried in'the tank 12.

By forcing air into the pipe 165, the exhaust from all of the suctionpumps can be utilized to agitate the'pulp mixture.

In applying vacuum to coat a lamination die with the pulp substance, itis preferable that the liquidmixture be allowed into the die in varyingvolumes, first in av comparatively small volume and then in "anincreased volume; accordingly, a suitable valve 169A controlled from themachine, is provided, whereby the liquid is sucked u into .or throughthelaminations in'the 'e (40 in Figure 1). is comparatively small, so as topermit of an intial coat of the pulp substance to be deposited upon thelaminations,

and then an increased flow turned on to complete the coating totherequired thickness.

Although it is stated herein that male dies are used for finishing thepulp articles,

in articles not requiring a. finished appearance, the male dies then areonly necessary to remove the articles.

But it must be expressly understood that 7 this invention is not limitedto or dependent upon the utilization of the exhaust for agitating thepulp solution, 'since any other agitating means. can be employed. It isto be noted that the vertical reciprocatinglmovement of the tank 12agitates the mixture;

but again, the invention is not limited or dependent upon the"OpeTatiOnL- fi'e causes the rota o he 'g'ears v21, '22 and oscillation.Oiglfl], j-.- evr's 28A and 29. The oscillation of thelevers 29causes;the 106 and 111: to alternately move toward and away from oneanother. As these links move toward one another, 108, and therefore theindexing 105, rotate e of a vertically moving i rotation. of the shaft19,

g'ears 22 causing the the discs 37A and plates 115 'ary. As the rotationof the shafts 35 and 105depends upon the rotation of the gears 22, itollows that these shafts will be rotated through 90 for every revolutionof said gears. Just before the discs 37A and 108 have completed theirperiodical anticlockwise rotation of 90, the dogs 134 cugage the lugs133A of the levers 132, forcmg the cam bars 125 to move toward the shaft35 and causing the indexing fingers 118 and 122 to disengage the notches116A in the indexing plates 115 and 116, respec- 4 tively. Before thedogs 134 have travelled sulficiently todisengage the lugs 133A, theindexing plates have rotated sufliciently to clear the notches from theindexing fingers.

shown in Figure 1', the

As'soon as the indexing plates, and therefore the shafts 35 and 105 haverotated through an angle of 90, the indexing fingers will travelupwardly under the action of the springs 130 and 131 to engage the nextnotches.

For every revolution of the gears 22, therefore, the cam bars willoperate to unlock and lock the shafts. While the gears rotate through180 from the position cam cranks 53 will remain stationary; whilethrough another 150, the cam cranks-53 will rotate in a clockwisedirection, causing the levers 55 to rotate in an anti-clockwisedirection, shifting the shaft 105 horizontally toward the shaft 35 andcompressing the springs 62; while the gears complete the revolution, thecompressed springs will cause the shaft 105 to shift back to theposition shown in Figure 1, and swing the levers bracket (40 inFigure 1) and lowers to clear 53 and 55 back to the position Figure 1.

While the shaft 35 is locked against rotashown in tion, the tank risesto immerse the female.

die or mold attached to the inverted die the die before the shaft 35 isrotated. For every four revolutions of the gears 22, the shafts 35 and105 will rotate one complete revolution, and for every revolution ofsaid gears, a female die will be temporarily locked in a position to beimmersed in the liquid contained in the tank. j

To each of the die brackets carried by the shaft 35 is detachablysecured a female die, and to each of the brackets carried by the shaft105 is secured the male die.

As the shafts 35 and 105 are momentarily locked against rotation, theshaft 105 is shifted horizontally toward the shaft 35, the

- male die engaging the corresponding female die to form the pulparticle andto remove 74; the tested pu p artlcle 111 therefore same fromthe female dieby suction.

the gears rotate The function of the vacuum chambers is to control thetime at which each .die is-to be subjected to suction or is to be opento the atmosphere, thefollowing beingja detailed N statement of theoperation of each vacuum chamber and the control effected thereby.

As has been explained before, the castings 143 and 144 are locked.against rotation while the shafts 35 and 105 rotate. When the diebracket 40is in the position shown .in Figure 1, the female" diewhich'it carries is in direct communication with the port 161 of the waxwasher,and therefore operatively. connected to the pipes 157 and 169 andto the vacuum tank 17 0 and pump 171. The suction created by the pump171 causes the water or solvent in the tank 12the die 40 now beingsubmerged-to flow through the laminations,

through the pipe line in the shaft 35, and' finally out of the pipe 169,a coating of the pulp substance being deposited upon the laminations'.The shaft 35 then rotates through an angle of 90, the die bracket 40moving to the position of the bracket 40A in Figure 1. i

As the bracket 40 is rotating, it will remain operatively connected-tothe pump 171 until the die bracket pipe line has reached the end of therecess 163, after which the suction from said pump will be out off. As

soon as the-bracket has completed its rotation of 90, the bracket 40willbecome operatively connected to the port 161A, the

pipes 157A and 166 and to the pump. 167, the suction being here utilizedto absorb the moisture in the pulp substance deposited upon thelaminations, or otherwise dry or drain said pulp. The bracket 40 is.again rotated through 90 and comes to a stop in the position of bracket40B in Figure 1.

The bracket 40 is operatively connected to the port 161B, to the pipes15713.- and 166," and to the suction pump 167, the process of drying thepulp substance on the lam1nat1ons 1.10 sumes its rotation to reach theposition of being continued. As soon as the bracket re bracket 40C inFigure 1, its communication I .the position of 108A in Figure 1, andcausing the engagement of the male die carried carried by the bracket40. 4

While the male die carried by the bracket 108B is in co-operativeengagement wlth the by said bracket 108B with the female diecorresponding female. die, the said bracket f is operatively connectedtothe port-5,161A of the wax washer carried by shaft 105, to the pipes157A and 173 and the suction pump be pulled out of the female die andinto the male die. As the shaft 105 then shifts back to its normalposition, the finished article is retained in the female die by suction.

' The bracket 40 will then resume its rotation of 90 until it is backinto the position shown in Figure 1. The bracket 100B then rotatesthrough an angle of 90 until it nected to the port 161C and to'the pipe157C,

and therefore to the atmosphere. The bracket 108C is then rotatedthrough another 90 to the position of bracket 108 in Figure 1, thebracket being open to the atmosphere. The pulp article is now ready'tofall off the female die, and a device or stripper is here-used for thisoperation, any suitable device now known to the art being used.
